Yes. Below is a snippet from the semctl(2) manpage on a Linux machine:

| SEM_STAT (Linux specific)
| 	Returns a semid_ds structure as for IPC_STAT.  However, the
| 	semid  argument  is  not  a  semaphore identifier, but instead
| 	an index into the kernel's internal array that maintains
| 	information about all semaphore sets on the system.

Yours,
